Optical Turnstile.

The new Student Center at Columbia College Chicago, located at 754 South Wabash Avenue in Chicago, opened its doors in the fall of 2019. This brand-new building offers five spectacular stories of spaces for students including music and film-screening rooms, dining options, a fitness center, a reflection room for meditation and prayer, and event spaces for meetings, performances, and receptions. Columbia College Chicago has a closed campus. In order to enter any building on campus students and staff must have a Columbia ID or visitors must have a valid appointment. The main entrance at the Student Center is the Tourniket revolving door that leads to a public foyer that includes a coffee shop and lounge. Since the speed gates are just past the security desk at the boundary of this area, they serve as a visual and physical indicator of where the public area terminates.

When it comes to physical security entrances, there are some different options available to choose from – high security portals, security revolving doors, speed gates, full-height and tripod turnstiles. These options vary greatly in their capabilities and can confuse security managers looking to secure their facilities from risk. To assist professionals in selecting the right entrance solution, we have categorised security entrances by their level of security, as it relates to tailgating mitigation. Is the goal: tailgating deterrence (low security level), detection (medium security level) or complete prevention (high security level).
